Question

The function f is defined by f x = 270 0.1 x . What is the value of f 0 ?

Accepted Answer

Choice D is correct. The value of f 0 is the value of f x when x = 0 . Substituting 0 for x in the given function yields f 0 = 270 0.1 0 , or f 0 = 270 1 , which is equivalent to f 0 = 270 . Therefore, the value of f 0 is 270 . Choice A is incorrect. This is the value of x , not f x . Choice B is incorrect and may result from conceptual or calculation errors. Choice C is incorrect. This is the value of f 1 , not f 0 .
